basalt tiles - will this dry ok?

[Tabby Cranks]

True stone store. Real Basalt is an igneous rock, so should be fairly dense, with a low water absorption pretty much like granite. In fact many dark granites sold are actually basalt.

Technodad... your problem is solely down to incorrect fixing methods by the builder..... Has he been informed of this and what was his reply?

aye he knows, he had to rip em up! we have them drying on radiators to see if the staining will go, hoping we can reuse them. looks like it might almost go but leave faint tide marks, really annoying. almost usable but not quite. might stick em in a garage for future patio or something.

With natural products that are prone to staining I was always told to dip the tile in the sealer. That way you do the front the back and the edges. You may seal the back of the stone to stop the adhesive staining the stone but if you neglect the edges you may get staining from the grout.

In my humble opinion it is not a job for a halfarsed builder it is not even a job for a run of the mill tiler it is a job for a specialist stone fitter.

 

[technodad]

so how much sealer you reckon i need for 20 sq m?

 

[kilty55]

that will depend on the product you buy technodad,if your going to use a tiler for the next attempt maybe best getting them to advise and do a test

4 or 5 liters maybe
